Embodiment 1

[0053] Embodiment one: according to percentage by weight, octadecyl trimethyl ammonium chloride 8%, cetyl trimethyl ammonium chloride 10%, dodecyl trimethyl ammonium chloride 17% and ethylene diethyl ammonium Alcohol 65% is uniformly mixed to obtain a trapping sedimentation agent.

Embodiment 2

[0054] Embodiment 2: According to weight percentage, 10% of octadecyltrimethylammonium chloride, 15% of cetyltrimethylammonium chloride, 60% of ethylene glycol and 15% of propylene glycol are uniformly mixed to obtain a trapping and settling agent .

Embodiment 3

[0055] Example 3: According to the percentage by weight, 12% of octadecyltrimethylammonium chloride, 10% of polyacrylamide 1% aqueous solution, 48% of ethylene glycol and 30% of glycerol were uniformly mixed to obtain a trapping and settling agent.

[0056] The embodiment of the present invention also provides a method for removing the catalyst solid powder in the oil slurry. The catalyst solid powder in the catalytic cracking oil slurry is removed by using the trapping and settling agent described in the above embodiment, which can speed up the process of removing the catalyst solid powder in the catalytic cracking oil slurry. The speed of sedimentation and separation from the oil slurry can effectively reduce the ash content or filterable particles of the oil slurry. Such as figure 1 As shown, it includes the steps:

[0057] 1. Take out the captured sedimentation agent from tank B with pump C, and make a homogeneous mixture with the FCC oil slurry sent by pump A with high-s...

Abstract

The invention provides a capturing settling agent and a method for removing catalyst solid powder in oil slurry, the capturing settling agent comprises the following components by weight percent: 0-50% of alkyl R quaternary ammonium salt, 0-40% of flocculant solution and 0-100% of polyol. The method accelerates the settling speed of the catalyst solid powder in the FCC oil slurry by adding the capturing settling agent, overcomes the insufficiencies of the prior FCC oil slurry solid removal technology through a set of complete combined technology of using the capturing settling agent, reduces the ash content of the FCC oil slurry below 0.05%w and provides the quality assurance for the follow-up utilization of the oil slurry.

Description

technical field [0001] The invention relates to the technical field of a settling agent and its application, in particular to a trapping settling agent for removing catalyst solid powder in catalytic cracking oil slurry and a method for removing catalyst solid powder in catalytic cracking oil slurry using the settling agent. Background technique [0002] FCC (catalytic cracking) oil slurry is an unconverted hydrocarbon with a boiling point greater than 350°C produced during catalytic cracking. FCC oil slurry has good economic value, but because FCC oil slurry contains 2000-9000ppm of catalyst solid powder, its economic scale and value-added utilization are greatly limited. Specifically in the following aspects: [0003] 1. When the catalytic oil slurry is used as a blending component of heavy fuel oil, if it is not purified, the catalyst solid powder in the oil slurry will wear the burner of the heating furnace, resulting in serious dust accumulation on the surface of the h...
